Unless you're going to be stranded somewhere, there's no need to stock up on tons of canned fruits. Or at least don't make them a part of your daily diet. Canned fruits are swimming in high-fructose corn syrup, which engenders such risks as obesity, high cholesterol and insulin intolerance. Some even contain artificial coloring (cherries, peaches). Word of advice: read the nutritional facts on the can and always favor freshly available seasonal fruits.
